Tons of bags in high temperature lifting test, because the load by 5 times is the collective force components at the same time, the force per unit area was 5 times of the rated load, if passed this test, then the test drop test and dumping height were 0.8M and 3M, with rated load at it's free fall, the sum of its weight and gravity acceleration than the 5 times when the load force is much smaller. The force of a high temperature resistant bag to all the parts of the whole bag is much smaller than 5 times the load and from the inside to the outside. It is not a threat to the product. In tear propagation, if more than 5 times of load is distributed on the 10CM of a carrier part, the force on the F is F. When the rated load is torn up, the force assigned to it is at the same place. The gravity direction of the contents of the bag body is mainly downward, and it has a certain pressure on the side wall fabric, but it is relatively small. The pressure is related to the height of the material surface, which is related to the size of the bag face, and is also related to the powder, granular, lump and density of the content material. At the same time, the pressure of weft yarn in vertical and horizontal direction, respectively, and will have two components to the flat bag in the longitude and latitude direction along the axis of blade at the end of 45 degrees vertically in the bag. Through the more complex calculation, we can get the two components. The tear propagation as a part of the overall load analysis of container bags is relatively complex. But practice has proved that when the rated load is applied, the knife edge will not extend.
